Global Ledger

Screen outbound transactions with Global Ledger’s blockchain analytics and KYT solution.

Global Ledger is a blockchain analytics company providing AML compliance and KYT (Know Your Transaction) solutions. Their platform supports over 2,000 digital assets and delivers real-time risk scoring for transaction screening.

Setup

1. Go to Settings > Integrations > AML in the Dfns Dashboard
2. Select the Global Ledger tab
3. Enter your Global Ledger API key
4. (Optional) If using an on-prem deployment, specify your custom base domain and supported blockchains
5. Save

Outbound transfer prescreening

Outbound transfers can be screened by Global Ledger before they are broadcast on-chain. To enable this, create a policy with:

• Activity kind: Wallets:Sign
• Rule kind: GlobalLedgerTransactionPrescreening
• Action kind: Block, RequestApproval, or NoAction

When the policy triggers

The policy triggers when either:

• The transaction’s risk score meets or exceeds your configured riskScoreThreshold (0-100 scale, where 100 is highest risk)
• Global Ledger returns any alerts for the transaction (alerts are configured in your Global Ledger dashboard)

When triggered, the policy approval page displays “Evaluation details” with the full response from Global Ledger, including risk scores and any alerts.

Skip options

The rule includes options to handle edge cases:

Option	Description
skipUnscreenableTransaction	Skip wallet requests that cannot be screened (e.g., raw signatures)
skipUnsupportedNetwork	Skip transfers to networks not supported by the integration
skipUnsupportedAsset	Skip transfers of assets not supported by the integration
skipGlobalLedgerFailure	Skip if the Global Ledger API request fails

When a skip option is enabled and the condition is met, the policy does not trigger and the transaction proceeds.

Webhook events

When the policy triggers, the screening results are included in the policy.triggered webhook event.

Supported networks

Global Ledger supports major blockchains including Bitcoin, Ethereum, Tron, BNB Chain, Solana, and more. For the complete list of supported networks and assets, see Global Ledger’s documentation.

If you’re using an on-prem deployment of Global Ledger, you can specify which blockchains your deployment supports in the Dashboard integration settings.
